RING ASSEMBLY Filed' Feb. 16, 1940 INVENTOR 59 so me. Rsmm Patented Mar. 4, 1941 PATENT OFFICE RING ASSEMBLY Elmer R. Stahl, Meyersdale, Pa., assignor to Celanese Corporation of America, a corporation of Delaware Application FebruarylG, 1940, Serial No. 319,259 6 Claims. (01. 57-120) This invention relates to a ring assembly and relates more particularly to an improved positive-lubricating ring assembly for use in the high speed spinning and twisting of yarn.

An object of my invention is the provision of a novel spinning ring assembly provided with means for uniformly lubricating the surface upon which the moving traveler bears.

A further object of my invention is to provide an improved lubricating means for a spinning ring assembly in which the supply of lubricant to the bearing surface is so controlled that neither loss of lubricant nor soiling of the yarn will occur.

Another object of my invention is to so locate said lubricant supply that any excess of lubricant upon the-above-mentioned bearing surface will be caught and returned to the main oil supp y.

Still another object of my invention is to provide a spinning ring construction which is adapted to increase the speed at which ring spinning and twisting devices may operate, thereby increasing the production of yarn.

Other objects of my invention will appear from the following detailed description of the invention.

In the accompanying drawing, wherein the preferred embodiment of my invention is shown,

Fig. 1 is a plan view of the ring assembly,

Fig. 2 is a vertical elevation of the ring assembly,

Fig. 3 is an enlarged cross-sectional view of the lubricating'mechanism, and is taken on the line 3-3 of Fig. 1, and

' Fig. 4 is a cross-sectional view of the ring with the traveler in position.

Like reference numerals indicate like parts throughout the several views of the drawing.

Referring specifically to the drawing, there is shown a spinning ring assembly, generally indicated by the reference numeral 5, which com- 'prises a bottom section 6 having integral bifurcated brackets 1 which are adapted to be attached to the ring rail, a top section 8 seated on and fixed to said bottom section as by means of screws 9 and a spinning ring Ill which is held in position by means of said top section as is well understood in the art. It is to be understood that the top section 8 and the ring l0 may be fabricated as a single piece. Said ring l0 may be any type of spinning ring adapted to be lubricated. The tapered bore ring shown is merely illustrative.

A reservoir II which holds the main oil supply is formed integral with the inner periphery of the bottom section 8. In order that this main body of oil is not unduly disturbed by any air currents created by the flanges of and/or the yarn package on the spindle mechanism revolving at high speed in close proximity thereto, a suitable baiile l2 of any suitable material which maybe inclined toward the body of the oil is supported by a lip l3; said lip with the upper free edge of the reservoir. This lip I3 and baflle I2 are so positioned that any oil dripping from the lower edge of the ring ill will be caught by the said lip and the surface of; the battle and returned to the reservoir. It is obvious, however, that other means may be utilized to serve as a battle to prevent the main body of oil being unduly disturbed.

The oil from reservoir II is drawn therefrom and forced toward the bearing surface IA of spinning ring H) by a piston l5 which is journaled in sleeve l6. The piston, when pressed downward, exerts a pressure and forces the oil out of the space or cylinder ll into which it had previously been drawn by an upstroke of said piston, through the connecting duct I8, past the ball check valve l9, into the oil duct 20 and then into a distributing manifold or header 2|. The distributing manifold 2| is an annular or sectional space formed at the junction of the top section 8 and the rear portion 22 of the ring l0. Manifold 2| is annular or sectional in form and may or may not extend along the full circumference of the spinning ring l0. Connected to said manifold are the wick holes 23 which supply the oil from said manifold to annular or sectional groove 24 which is situated at the upper edge of the bearing surface I4 and thence by gravity to the bearing surface ll of the spinning ring. The manifold 2| and/or the wick holes 23 are filled with wicking or other porous material to prevent the oil from Spurting and to give a uniform flow of oil to the oil groove 24 and down over the bearing surface N. This construction causes the oil to be properly distributed to the bearing surface It and to lubricate said surface and the moving traveler 25 bearing thereon as shown in Fig. 4.

When the piston I5 is released after the downward stroke it is forced back to the top of the stroke by a spring 26 bearing on the extension 21 which may be integral with the top of the piston. The length of stroke of the piston may be adjusted by the screw 28. The release of the piston creates a suction which unseats a.

ball check valve 29 while firmly seating ball check valve.i9. This suction draws oil from the reservoir H through the connecting oil duct and past the check valve 29 and at the same time forces the oil into the connecting oil duct l8 and the cylinder l1.

0n the downward stroke of the piston the ball check valve 29 is seated, check valve i9 is unseated and the oil-passes upward and outward through oil duct 20 into the manifold 2|, is then distributed to the wick holes 23 and thence to the oil groove 24 and to the bearing surface 14.

In conjunction with the oil ducts there may be an air cylinder 3| located directly over the enlarged section of the oil duct containing the The purpose of this air cylinder is to provide a cushion of air to absorb the transmitted shock of the downward stroke of the piston i5 and to slow or control the flow of oil to the oil groove "24.

The piston is preferably located towards the back edge of the ring rail and is actuated at each upward stroke of the ring rail which causes extension 21 to come into contact with a stationary arm (not shown) suitably positioned on the machine frame in the path of said piston, It is obvious, however, that other means may be utilized for actuating the piston since any other movement which regularly or intermittently depresses the piston will force the lubricant through the connecting ducts and out on to the bearing surface ll. h

If desired, an external orifice or well with a connecting duct to the reservoir Il may be pro-- vided for the indication of the level of oil in said reservoir i l Suitable means for replenishing the supply of oil when necessary may be provided in connection with said well and duct.

The mechanism herein described for the auto-- matic lubrication of the traveler bearing surface permits yarn to be wound and twisted with higher traveler speeds than have heretofore been possible. Although traveler speeds may be raised there is no noticeable increase in wear on the traveler or in breaking of ends, nor is there any reduction in the uniformity and quality of the yarn.

It is to be understood that the foregoing de-' tailed description and drawing are given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.
